Conventions
Many examples of commands, SQL statements, and code are included throughout the
book. Specific keywords are written in uppercase bold. For example: A NULL value
represents an unknown state. Commands are shown in lowercase bold. For example: The
dir command lists all files and subdirectories on Windows. SQL statements are shown in
upper case bold. For example: Use the SELECT statement to retrieve information from a
table.
Object names used in our examples are shown in bold italics. For example: The flights
table has five columns.
Italics are also used for variable names in the syntax of a command or statement. If the
variable name has more than one word, it is joined with an underscore. For example:
CREATE TABLE table_name
